on skew power series-wise mccoy rings

Let $r$ be a ring with an endomorphism $alpha$‎. ‎a ring $r$ is a skew power series mccoy ring if whenever any non-zero power series $f(x)=sum_{i=0}^{infty}a_ix^i,g(x)=sum_{j=0}^{infty}b_jx^jin r[[x;alpha]]$ satisfy $f(x)g(x)=0$‎, ‎then there exists a non-zero element $cin r$ such that $a_ic=0$‎, ‎for all $i=0,1,ldots$‎. ‎we investigate relations between the skew power series ring and the standard ring-theoretic properties‎. ‎moreover‎, ‎we obtain some characterizations for skew power series ring $r[[x;alpha]]$‎, ‎to be mccoy‎, ‎zip‎, ‎strongly textit{ab} and has property (a)‎.
